The hannya (般若) is a mask used in Japanese Noh theater, representing a jealous female demon. It is characterized by two sharp bull-like horns, metallic eyes, and a leering mouth.
Though the overall story and appearance of the mask may seem dark, the word Hannya in Japanese actually means “wisdom” and the masks themselves are considered a symbol of good luck.
The Hannya Adjustable Steel Ring is made of stainless steel, a nickel and molybdenum alloy known for its sturdiness and corrosion resistance.
